I'm going to be at Casual Connect (June 21-22) next week in Seattle on behalf of Aurora Feint / OpenFeint. Let me know if you want to meet up and learn how OpenFeint can make your games more social and how you can cross-promote your games on the OpenFeint platform.
Oh BTW, OpenFeint just announced the OpenFeint 2.0 social community platform for mobile games :
OpenFeint Social Discovery
OpenFeint Social Discovery supports multiple approaches to discovering games and game content in the App Store
Discovery Lobbies: Chat with other people from any OpenFeint enabled game and discover what they are playing. See the name of the game every player is chatting from alongside each and every message. Clicking on the game's name or icon will take you its iPurchase Catalog where you can click Buy Now to go directly to the app store and purchase the game.
What are my friends playing:
Clicking on a person in the friends tab shows you a list of all the OpenFeint games they have played. Clicking on any of those games will take you to its iPurchase Catalog page from where you can click Buy Now to go directly to the app store and purchase the game.
Social Challenges: Send a challenge to your friends including those even playing a different game! Your friend will receive the challenge when opening any OpenFeint enabled title. From there, they can see click to the challenge information and are given the option to purchase your game from iPurchase if they don't already own it.
